Background: Pharmacoinvasive strategy is an effective myocardial reperfusion therapy when primary percutaneous coronary intervention (p-PCI) cannot be performed in a timely manner. Methods: Authors sought to evaluate metrics of care and cardiovascular outcomes in a decade-long registry of a pharmacoinvasive strategy network for the treatment of ST-elevation myocardial infarction (STEMI). Data from a local network including patients undergoing fibrinolysis in county hospitals and systematically transferred to the tertiary center were accessed from March 2010 to September 2020. Numerical variables were described as median and interquartile range. Area under the curve (AUC-ROC) was used to analyze the predictive value of TIMI and GRACE scores for in-hospital mortality. Results: A total of 2,710 consecutive STEMI patients aged 59 [51–66] years, 815 women (30.1%) and 837 individuals with diabetes (30.9%) were analyzed. The time from symptom onset to first-medical-contact was 120 [60–210] minutes and the door-to-needle time was 70 [43–115] minutes. Rescue-PCI was required in 929 patients (34.3%), in whom the fibrinolytic-catheterization time was 7.2 [4.9–11.8] hours, compared to 15.7 [6.8–22,7] hours in those who had successful lytic reperfusion. All cause in-hospital mortality occurred in 151 (5.6%) patients, reinfarction in 47 (1.7%) and ischemic stroke in 33 (1.2%). Major bleeding occurred in 73 (2.7%) patients, including 19 (0.7%) cases of intracranial bleeding. C-statistic confirmed that both scores had high predictive values for in-hospital mortality, demonstrated by TIMI AUC-ROC of 0.80 [0,77–0.84] and GRACE AUC-ROC of 0.86 [0.83—0.89]. Conclusion: In a real world registry of a decade-long network for the treatment of ST-elevation myocardial infarction based on the pharmacoinvasive strategy, low rates of in-hospital mortality and cardiovascular outcomes were observed, despite prolonged time metrics for both fibrinolytic therapy and rescue-PCI.

Importance: Heart failure (HF) and aortic stenosis (AS) frequently coexist, presenting a complex clinical challenge due to their intertwined pathophysiology and associated high morbidity and mortality. Despite numerous advancements in transcatheter and surgical aortic valve replacement (AVR), HF decompensation remains the leading cause of cardiac rehospitalization and a major predictor of mortality in patients with AS, before or after AVR. This review aims to provide a comprehensive analysis of the interplay between AS and HF, delving into myocardial changes caused by stenotic insult, the impact of AVR on these changes, and the prevalence and contributing elements of HF before and after AVR., Observations: The prevalence of HF remains high before and after AVR, particularly among patients with left ventricular dysfunction. Increased afterload from AS causes cardiac remodeling, which is initially benign but over time these changes become maladaptive, contributing to HF and increased mortality. The progression of HF is influenced by the degree of reverse cardiac remodeling, which can be affected by comorbid conditions, the hemodynamic performance of the valve prosthesis, and vascular stiffness. Several blood and imaging biomarkers offer insights into underlying AS pathophysiology, serving as mortality predictors and predicting HF in this patient population., Conclusions and Relevance: HF development in AS is multifactorial and its link to left ventricular dysfunction is a complex process. Delineating the determinants of HF admissions in AS is crucial for identifying individuals at high risk. Identifying the early signs of left ventricular decompensation by using surrogate markers may be the key, even before left ventricular function becomes impaired. Translating multimodality imaging techniques and biomarkers into routine clinical practice for evaluating cardiac damage and integrating these markers with patient and procedural factors that affect HF before and after AVR can facilitate timely intervention, minimizing the likelihood of HF progression and influencing future guidelines.
